I am researching by asking someone posting and starting a thread with knowledge of an interesting breed . II'm curious , since they came with the settlers, where are the purebred examples of the breed here in the new world? Were the pure lines diluted over time? I suspect thats what happened.
dilute. I think so then transformed into new breeds. I think a combination of things happened as the conquest was happening. Both French and Spain settled the coast lines and inland. Battles won and lost against the natives, themselves, as they moved conquered and colonized. Then trades for goods, spices and animals for gold as they began to settle these areas and then send gold and goods back the Kings. Trades such as the mustang horse brought native Americans, like the plains Indians, down to Mexico area for trading. This could have spread the old world breeds with the native American dog. But I bet Mother nature took a hold as the war dogs bred native dogs. I would think the same with the guard dogs running with herding dogs. Some old writings talk about the landrace breed and it's importance to the new world. Not just dogs, but other stock. Landrace dogs may be something for you to look into too. Gotta remember we had wild game that these war dogs, guard dogs and herding dogs never seen before. Funny too how a "mastiff" covered a wide verity of dogs. Same with the old world hounds or hunting dogs.
good little thread you got going.
